No shopping without a smartphone? At Amazon & Co. that’s true today already – but even in the shop next door this could be the future. Lots of apps in stationary retail. But: not to order and be delivered home. In the future, the phone will be in use while shopping in the store, to find out if the missing size is still in the warehouse. Even concerning shopping sprees where it is about touching, trying on and looking in the mirror soon digital technology will be part of the picture.
